TRICYCLE.

SPECIFICATION forming part of Letters Patent No. 340,617, dated April27, 1886.

Application filed May 13, 1885.

To all whom, t may concern:

Be it known that I, HENRY A DDIsoN ROB' INson, of Foxcroft, in thecounty of Piscataquis, of the State of Maine, have invented a new anduseful Improvement in Tricycles; and I do hereby declare the same to bedescribed in the following specification and represented in theaccompanying drawings, of which- Figure l is a perspective view of atrioycle provided with my invention, the nature of which is defined inthe claims hereinafter presented. Fig. 2 is a top view, and Fig. 3 aside elevation,ofthe arm employed in carrying out my improvement.

In using a tricycle, especially of the kind usually termed the Columbiatricycle, a perspective View of which is shown in Fig. l, there isexperienced by the rider a very annoying jar and trembling of the handleof the mechanism for steering the machine, such being caused by thesteering-wheel in its passage over irregularities in the surface of aroad. This tremblingA or unsteadiness of the steering-wheel while thetricycle is in use is communicated through the wheelsupporter, thesteering-arm, and thence by the tillerlrod to the steeringhandle. As aremedy for such trembling of the said handle, which, besides theannoyance created by it to the rider, is liable in time to injuriouslyaffect the nerves of his hand and arm, the handle` rod has been providedwith an auxiliary supporting-arm to extend from the main horizontalshaft or bar, which is over and parallel with the axle. and inclineforward and upward, such arm at its front end clasping or encircling thesaid rod close to the handle thereof. In practice such arm has been acomplete remedy for the aforesaid evil. Prior to my invention this armhas been integral with the ordinary lower supporting-arm, the two beingthe prongs of a fork. This makes the auxiliary arm a part of thestructure of the tricycle, and specially belonging to it.

Serial No. 165,380.

Such

(No model.)

construction does notpermit the arm to be applied to any kind oftricycle. I make this auxiliary supporting-arm as a device which can beslipped onto any kind of tricycle, as.

there are only two points of adjustment. It can be slipped off if notwanted, and is a separable attachment to a tricycle. I usually line orbush with leather or some other proper soft material the arm-bearingthrough which the rod extends. The said arm I usually make of steel, itbeing provided at its rear end with a tubular eye, a, to receive theshaft, and at its front end with another such eye, b', to receive thehandlerod, all being as represented in the drawings, in which- A A arethe larger wheels, and B the steering-wheel, of a tricycle; O, the axle;D, the shaft or bar over such axle; E, the steeringmechanism handle, anda the rod to which such handle is aixed. This rod, pivoted at its lowerend, is supported by an arm, b, extending horizontally, or thereabout,from the said shaft, the rod going through such arm. Over the saidarm,and projecting forward and upward, as shown, is the supplementaryarm G, which rises from and is fastened to the shaft and extends nearlyif not quite upto the handle, which necessarily has to be some distance,as shown, above the main arm.

l. As an attachmentfor a tricycle, the supplementalsteeringrod-supporting arm O, having the eyes a b', as set forth.

2. In a tricycle, the combination of the bar D, the-steeringrod a, theordinary steeringrod-supporting arm b, and the supplemental HENRYADDISON ROBINSON.
